Yes, we are working very hard, as a matter of fact! We keep in touch with our supporters constantly. You can always talk to us on the forum, check up on our ModDB page, Facebook or Twitter.

Release a media update!

Media updates are a very time consuming procedure, which is why we prefer to focus on mod development as our first priority.
Think of it this way: The less media releases, the harder we are working on our mods. Besides, releasing too much content out front will spoil your experience of the final product.

How much of your projects is done? How about a release date?

We cannot estimate the exact percentage of completion, neither an approximate release date. You can get a rough idea of our progress by looking at our media updates.
Until we are 100% sure we can make it and the exact release date is announced via a major update, don't bother asking developers about it. You will not get the answer.
